It's easy to pick out the domains which need focus and optimize in bulk.
Screaming Frog allows you to export data to Excel or Google Sheets for bulk editing, and also integrates with Google Search Console and Google Analytics so that you can overlay important traffic and website ranking information when dissecting data.
There really isn't much that Screaming Frog doesn't handle as an SEO audit tool. It can be used to find broken links, audit page titles and meta descriptions, visualize link architecture, highlight duplicate content, check indexability and redirects, generate sitemaps, and more.

When using the Semrush SEO audit tool, you start by configuring how many URLs you want to audit, and the crawl source for your audit (you can use the website itself, sitemaps, or custom URLs that you upload from an Excel file).
Semrush then generates a dashboard based on your crawl results to show you the overall health score for your website, alongside the errors, warnings, and notices that you need to focus on to improve overall site health.
Here's a snapshot from our Visualize Value Semrush SEO audit.
When errors are identified, it's easy to drop down and see the source of the error, as well as the URLs impacted and the changes that you need to make in order to remove that error.
